To (all 'wl/,0711, t 'nt/ty colt/:07%.-

Be it known that l, AeNns H. Rioniiniillnn, a citizen of the UnitedStates, residing' at St. Louis, in the State oi' Missouri, have inventedcertain new and useful Improvements in Cord Attachments ForVVindow-Shades, oitl which the following' is a specification, referencebeing' had therein to the accompanyi ng' drawin This invention relatesto improvements in a cord attachment for window-shades; and it consistsin the novel arrangement, construction, and combination of parts, aswill be fully hereinafter described and claimed.

The object ot this invention is to construct a device to be attached tothe stil'iening'bar ot' the window-shade, the said device containing'the regulating-cord.

A 'further object is the cord is normally concealed from view by being'retained within a casing' by a spring-drum, yet permitting the cord tobe partially withd 'awn for the adjustment oi' the shade.

Figure l is a perspective view ot' a windowshade, showing' the improveddevice in position, the cord partially withdrawn. Fig'. Q is a verticalsectional view taken through the casing', showing' its internalconstruction. Fig'.

3 is a vertical cross-sectional view ol the saine,

showing' its construction and relative to the shade.

lin the construction ot' the device as shown, l indicates a casing'provided with a verticali projecting' flange 5, located at one side-thereof, and provided with suitable screw-holes through which screws,brads, or the like may be inserted for attaching' said device to the Theeasing' il has also a housing' 7, in which is located a revolving'spring' actuated drum 8, loosely mounted upon a stationary .shal't 9,the said shaft being' supported in the casing' 4. A i'lang'e l0 isformed on one side ol'l the drum 8 and provided with notches ll, inwhich is adapted to eng'ag'e the pawl l2, which is pivotally connectedto the side wall of the casing'li. (See Fig'. 2.) To the outercircumference ol" the drum proper is secured one end of the cord 13, andaround said drum the said cord is wound.

The cord is prevented trom leaving' the position 777,140, dated December13, 1964. Serial No. 172,214. (No model.)

drum by means of the llang'ed edge 14. A hole 15 is termed in the bottomot' the casing' 4, through which the opposite end ot' said cord ispassed and attached to a knob lli, by which the operator may partlywithdraw said cord when desiring' to adjust the position oi'l the shade.

A spiral spring' 17 is located within the drum 8, one end thereol."rig'idly secured to the inner periphery and theother end rigidly securedto the shaft 9.

lily pulling' upon the cord i3 the drum will revolve within the casing',at the same instant winding' up the spiral spring' until its movement islimited. The shade is then adjusted, and by instantly releasing' saidcord the same will be rewound upon the drum bythe unwinding' o'lj thespiral spring' until the knob comes in contact with the casing',completely concealing' the cord 'from view.

lf desired to have the cord or a portion thereof to project trom thecasing', it is allowed to slowly rewind until the pawl l2 eng'ag'es thenotch ll in the liang'e.

lhe device is made ornamental and dispenses with the inconvenience ofthe common cord and marring` ol the woodwork. lt has features of noveltyand utility.

Alila-ving' tully described my invention, what I claim, and desire tosecure by Letters Patent, is

l. A device ol the class described comprising' a casing',a llang'eprojecti ng' up wardly from said casing', said device attached to thestillening'bar ol'l the window-shaifle, a drum, a shaft for supporting'the drum within the casing', flanges .formed on each side olf the drinn,a cord secured to the drum and adapted to wind around the same betweenthe flanges, a spiral spring' located inthe drum for controlling' saiddrum when manipulated by the action oit' the cord substantially asspecified.

2. A wirulow-shade provided with means for :uljustably securing-its cordthereto, said means comprising' a casing' having' devices by which it issecured tothe stillei'ling'bzn' of said shade, and a housing' having` anopening' at one end only through which the cord is adapted to he drawn,a drum rotatably mounted in said housing and to which one end of saidcord is IOO housing and to which one end of said cord is secured, and aspring connected with said drum and serving to rotate the saine in onedirection so as to draw the cord into the housingl when the cord isreleased.

ln testimony whereof l aHiX my signature in presence of two witnesses.
